The German Military Stiletto Knife measurers 5" when closed. It has intricate scrollwork on the hilt and bolster. There is a military emblem on the black handle.
A stiletto is a long, narrow-bladed dagger. This dagger is designed as a stabbing weapon, rather than for cutting, since its long narrow shape allows it to penetrate deeply in a point.
The stiletto began to gain fame during the Renaissance when it was popular as a tool against heavily armoured knights. The thin blade could easily pass through most chainmail, or find its way through tiny gaps in a knight's armour.
The stiletto was also favoured amongst assassins because it was an easily concealed weapon. This tactic occurred repeatedly, from the Zealots of 1st century Judaea, to the Venetians, to the Assassins of Alamut.
